Using the Lezyne Macro Drive 1400+ Front Light is easy. First, charge it via the USB - C port until it's fully charged. You can then attach the light to your handlebar using the durable strap. Press the button on the light to cycle through the seven different output modes and choose the one that suits your needs. When riding in bad weather, you don't have to worry as it's waterproof. But try to dry it off after use. For maintenance, keep the charging port clean and store it in a cool, dry place when not in use. This will help ensure your light stays in good working condition for a long time.
